Hi, guys! I haven’t started my thesis yet, but December 22th is the deadline. Could any of you give me some suggestions? The thesis is about laser technology and the relevant products, such as
laser beam pointer pens, so I chose green
laser pen as the subject. Searching on the Internet, I found there are a variety of laser pointers like
30mW Green Laser Pointer pens. Besides, some laser pens are for some specific purposes like
high power green laser pointer pens can weld metals. Some kind-hearted
wholesalers even gave me some help with my thesis, but not all the people who
wholesale laser pointer are willing to help me and I do not think it is enough for me, so could anyone who has ever bought
wholesale laser pens or used
50mw green laser pens give some help pls? I’m looking forward to your reply. Thanks a lot!
